Turbine Engine Transmission Gutter

摘要

A turbine engine case defines a centerline and a gaspath within the engine case. A fan is coupled to a fan shaft. A transmission couples the shaft to the fan shaft to drive the fan and comprises a gear system. A gutter system is positioned to capture lubricating fluid slung from the gear system. The gutter system includes a gutter extending partially circumferentially about the centerline having a first circumferential end edge. An inlet channel has an inlet at the gutter first circumferential end edge and locally radially outboard of the gutter. At least one vane is spaced apart from the gutter first circumferential end edge.

1. A gutter system for capturing lubricating fluid slung from a gear system comprising:
a gutter extending partially circumferentially about a centerline and having a gutter first circumferential end edge; an inlet channel having an inlet at the gutter first circumferential end edge and locally radially outboard of the gutter; and at least one vane spaced apart from the gutter first circumferential end edge, the at least one vane positioned with a chord oriented with a component from an outboard edge to an inboard edge circumferentially in the same direction as an inlet flow direction.
